The Harold K.L. Castle Foundation is proud to continue to support the Ko‘olau Pilina Fund in 2025. Now in itʻs fourth year, the fund prioritizes projects specifically tailored to Ko‘olau communities on Oʻahu from Kahuku to Makapuʻu. Read about the first-year Pilina Fund pilot.
The purpose of the Koʻolau Pilina Fund (the fund) is to build community resilience in the Koʻolau region and follows a participatory approach to grantmaking in which a committee made up of Ko‘olau community members will vet proposals through an open, rolling application process. The committee hopes to help derisk new ideas, scale promising ideas, help to build capacity in the region and progress grassroots community efforts.
Application submissions are now being accepted for 2025.

Ola Ka ʻĀina, Ola Ke Kanaka: It is important that these funds support both healthy people and healthy lands. If our land thrives, so do we as a Koʻolau community.

The fund will support projects that understand the unique needs of our neighbors and find creative solutions to meet these needs.
